HelicalBar™ — Crack stitching and structural reinforcement for cracked walls.

Non-Invasive. Permanent. Guaranteed.

No part of the wall needs rebuilding. Keep existing — save thousands.

Fixing your home's walls with the right solution matters. After 15,000+ homes and structures repaired, one thing's clear: without the right structural fix, the cracks come back. Underpinning stabilises the ground (we do that too if needed) and surface patching makes the wall look good — but neither reconnects the wall. Without crack stitching or structural reinforcement, load can't transfer evenly across the wall, the crack returns, and you're back to square one.

HelicalBar™ removes that risk by structurally reinforcing your walls. A non-invasive solution that keeps existing walls in place — the bars install through narrow slots in the mortar beds, completely hidden from view, or through targeted points on rendered walls. Over 80 times the tensile strength of the bricks, HelicalBar™ bars reinforce across the crack or extend several metres beyond if required, tying the damaged section back to solid masonry so weight spreads evenly again. That's the difference.

What was the weakest point in your wall becomes the strongest. HelicalBar™ wall crack repairs can be applied to all types of masonry walls — brick, render, and stone. Heritage to new build, inside and out. Most jobs take just a day or two — you'd never know the wall had ever cracked.

Not sure if your walls need reinforcing, your foundation stabilising, the surface cosmetically patched, or all three? That's exactly what the free assessment answers.

Fixing Your Wall Cracks

On the scheduled day, our technicians arrive and get straight to work — marking out the wall, cutting neat slots into the mortar joints, and bonding HelicalBars™ into the brickwork with high-strength structural grout. The result: a reconnected, reinforced wall right where it’s needed most.

Final Touches & Clean-Up

Once the HelicalBars™ are installed, the finishing begins. Mortar is repointed, cracks filled, and brickwork colour-matched — or render and plaster blended for a smooth, uniform finish. Then the site is cleaned up and your home left spotless.

The benefits of a HelicalBar™ wall crack repair.

HelicalBar™ stainless steel bars are bonded into the mortar joints, reconnecting cracked masonry as a single structural unit — permanently. The wall is stronger than it was before the crack appeared, with load spreading evenly across the wall again — helping support the foundations by distributing weight the way the structure was designed to work. Works on all masonry — brick, render, or stone — inside or out.
